php--------返回404状态

php header()返回404状态代码的两种方式

    //方式一
    header('HTTP/1.1 404 Not Found');exit('404')
    //方式二  
    header("status: 404 Not Found");exit('404')

 

php header()函数的其他请求返回状态:

      1. 页面没找到 Not Found
  
  header(‘HTTP/1.1 404 Not Found’);
  
  2. 用这个header指令来解决URL重写产生的404 header
  
  header(‘HTTP/1.1 200 OK’);
  
  3. 访问受限
  
  header(‘HTTP/1.1 403 Forbidden’);
  
  // The page moved permanently should be used for
  
  // all redrictions, because search engines know
  
  // what's going on and can easily update their urls.
  
  4. 页面被永久删除,可以告诉搜索引擎更新它们的urls
  
  header(‘HTTP/1.1 301 Moved Permanently’);
  
  5. 服务器错误
  
  header(‘HTTP/1.1 500 Internal Server Error’);
  
  6. 重定向到一个新的位置
  
  header(‘Location: .example.org/’);
  
  7. 延迟一段时间后重定向
  
  header(‘Refresh: 10; url=.example.org/’);
  
  echo 'You will be redirected in 10 seconds';
  
  8. 加载要下载的文件:
  
  readfile(‘example.zip’);
  
  9. 也可以使用HTML语法来实现延迟
  
  header(‘Content-Transfer-Encoding: binary’);
  
  10. 禁止缓存当前文档:
  
  header(‘Cache-Control: no-cache, no-store, max-age=0, must-revalidate’);
  
  header(‘Expires: Mon, 26 Jul 2010 05:00:00 GMT’);
  
  header(‘Pragma: no-cache’);
  
  11. 显示登录对话框,可以用来进行HTTP认证
  
  header(‘HTTP/1.1 401 Unauthorized’);
  
  header(‘WWW-Authenticate: Basic realm=“Top Secret”’);
  
  echo 'Text that will be displayed if the user hits cancel or ';
  
  echo 'enters wrong login data';
  
  12. 设置内容类型:
  
  header(‘Content-Type: text/html; charset=iso-8859-1’);
  
  header(‘Content-Type: text/html; charset=utf-8’);
  
  header(‘Content-Type: text/plain’); // plain text file
  
  header(‘Content-Type: image/jpeg’); // JPG picture
  
  header(‘Content-Type: application/zip’); // ZIP file
  
  header(‘Content-Type: application/pdf’); // PDF file
  
  header(‘Content-Type: audio/mpeg’); // Audio MPEG (MP3,…) file
  
  header(‘Content-Type: application/x-shockwave-flash’); // Flash animation
